Abstract:
Studies on screening of soybean genotypes for the resistance against sucking insect pests of soybean was carried out during Summer, 2021. Out of the twenty soybean genotypes screened for field resistance against sucking insect pests, the genotypes DLSb 1 and DLSb 2 were found to be highly resistant to whiteflies, leaf hoppers and thrips. The genotypes SL 958 and SL 979 were resistant to sucking pests and DSb 21 exhibited moderate resistance to sucking pests. The above mentioned genotypes registered highest seed yield as well as lowest Yellow Mosaic Virus (YMV) incidence and can be used for breeding programme for developing insect resistance. The studies on correlation between sucking pests incidence and leaf characteristics of different soybean genotypes exhibited a significant positive correlation of whitefly incidence with leaf trichome density (r = 0.564), whereas leaf hoppers and thrips exhibited a non-significant negative correlation with trichome density and all three sucking pests were non-significantly correlated with leaf thickness.
